<p>Since exhaustive patterns and uninhabited types were brought up by <span class="user-mention" data-user-id="125270">@scottmcm</span>... what is the status of <code>!</code>? AFAIK <a href="https://github.com/rust-lang/rust/issues/67225">https://github.com/rust-lang/rust/issues/67225</a> is the latest issue. What is blocking progress here?<br>
I'd be delighted to finally see this type land, and wonder if there's any way I can help.^^</p>

<p>Last I remember there were type inference problems, but that could have been a different attempt at stabilization</p>

<p><a href="https://hackmd.io/KiXlJ-m5Sz6Rs7F9JadNqg?edit">https://hackmd.io/KiXlJ-m5Sz6Rs7F9JadNqg?edit</a> is my latest draft -- just written up -- of a possible summary / next steps issue for never type; I expect to iterate a bit more and likely file that as a T-lang design meeting proposal so we can discuss it, though possibly not this next round. I'd like to find some time to implement the hybrid 2 proposed there and make sure it addresses the breakage as expected.</p>
